Assessment of reconstructive procedures for femoropopliteal artery occlusive disease.

Abstract

A total of 117 consecutive reconstructive procedures for femoropopliteal arterial occlusive disease in 105 extremities of 101 patients have been reviewed. The types of procedures included 10 homografts, 28 Dacron and Teflon prosthetic grafts, 16 thromboendarterectomies and 63 vein bypass grafts. There were three postoperative deaths.The results of autogenous vein bypass grafts, as indicated by an early success rate of 90% and late patency rate of 76%, are superior to those obtained by other methods of reconstruction in the institution where this study was made.Early failure of these grafts in most instances relates to technical errors which can be reduced by meticulous surgical technique, operative angiography and close postoperative follow-up with early correction.Some of the late failures can be attributed to stenosis of the graft rather than to the progressive nature of the arteriosclerotic disease. Repeated followup examinations of the extremity at regular intervals and early angiography in the patients with return of symptoms may allow correction of the graft defect and salvage of the extremity.
